**I Built a Tool That Simulates and Detects Linux Rootkits**

There is something about the way rootkits work that I find genuinely fascinating. They do not break into a system; they hide inside it. They manipulate the operating system’s own interfaces to make themselves invisible. A process running on your machine that ps cannot see. A network connection that netstat will never show you. Files that ls refuses to acknowledge exist.

I became obsessed with understanding how that works at a technical level. Not just reading about it, but actually building it.

So I built RootWatch.

**What it does**

RootWatch is a Linux rootkit simulation and detection framework. It implements eight techniques used by real-world rootkits and then runs a detection engine that catches them by reading the OS directly bypassing the hooks a rootkit would install.

The simulation
